Описание: Get a feel for your art--literally 101 Textures in Colored Pencil teaches you every technique you'll need to give your colored-pencil drawings realistic, palpable texture. *Named One of the 54 Best Colored Pencil Drawing Books of All Time by BookAuthority* There has never been a better opportunity to master textures. Knowing how to make your surfaces and textures look real is one of the most challenging aspects of creating art in colored pencil, even for experienced artists. 101 Textures in Colored Pencil provides artists with step-by-step instructions for drawing a wide variety of the most common textures and surfaces, including sand, water, metals, foliage, wood, fabrics, stone, grass, hair, and many more. To get you started, this comprehensive guide opens with a review of tools and materials as well as basic skills, such as strokes, effects, and color mixing. Each page of instruction is a comprehensive resource on how to create a specific texture, complete with two to three easy-to-follow steps and a final, detailed image of the finished artwork. Plus, the book is organized into sections based on subject matter, so you can easily find the specific texture you're looking for. An artist's gallery in the back of the book provides examples of the textures in completed works of art. Just a sample of the textures you will learn to render:
Food & Beverage: red wine, cut citrus fruit, coconut, peach, dark chocolate
Nature: smooth and rough bark, moss, river pebbles, still and rippled lake, clouds
101 Textures in Colored Pencil includes all the textures you need to create realistic masterpieces in colored pencil.

Описание: The representation theory of Lie groups plays a central role in both clas- sical and recent developments in many parts of mathematics and physics. In August, 1995, the Fifth Workshop on Representation Theory of Lie Groups and its Applications took place at the Universidad Nacional de Cordoba in Argentina. Organized by Joseph Wolf, Nolan Wallach, Roberto Miatello, Juan Tirao, and Jorge Vargas, the workshop offered expository courses on current research, and individual lectures on more specialized topics. The present vol- ume reflects the dual character of the workshop. Many of the articles will be accessible to graduate students and others entering the field. Here is a rough outline of the mathematical content. (The editors beg the indulgence of the readers for any lapses in this preface in the high standards of historical and mathematical accuracy that were imposed on the authors of the articles. ) Connections between flag varieties and representation theory for real re- ductive groups have been studied for almost fifty years, from the work of Gelfand and Naimark on principal series representations to that of Beilinson and Bernstein on localization. The article of Wolf provides a detailed introduc- tion to the analytic side of these developments. He describes the construction of standard tempered representations in terms of square-integrable partially harmonic forms (on certain real group orbits on a flag variety), and outlines the ingredients in the Plancherel formula. Finally, he describes recent work on the complex geometry of real group orbits on partial flag varieties.
Описание: This book gives a self-contained account of applications of category theory to the theory of representations of algebras. Its main focus is on 2-categorical techniques, including 2-categorical covering theory. The book has few prerequisites beyond linear algebra and elementary ring theory, but familiarity with the basics of representations of quivers and of category theory will be helpful. In addition to providing an introduction to category theory, the book develops useful tools such as quivers, adjoints, string diagrams, and tensor products over a small category; gives an exposition of new advances such as a 2-categorical generalization of Cohen-Montgomery duality in pseudo-actions of a group; and develops the moderation level of categories, first proposed by Levy, to avoid the set theoretic paradox in category theory.The book is accessible to advanced undergraduate and graduate students who would like to study the representation theory of algebras, and it contains many exercises. It can be used as the textbook for an introductory course on the category theoretic approach with an emphasis on 2-categories, and as a reference for researchers in algebra interested in derived equivalences and covering theory.

Описание: The Seventh ARTA ('Advances in Representation Theory of Algebras VII') conference took place at the Instituto de Matematicas of the Universidad Nacional Autonoma de Mexico, in Mexico City, from September 24-28, 2018, in honor of Jose Antonio de la Pena's 60th birthday. Papers in this volume cover topics Professor de la Pena worked on, such as covering theory, tame algebras, and the use of quadratic forms in representation theory. Also included are papers on the categorical approach to representations of algebras and relations to Lie theory, Cohen-Macaulay modules, quantum groups and other algebraic structures.

Описание: It presents several themes of contemporary representation theory together with some new tools, such as stable ?-categories, stable derivators, and contramodules. In the first part, expanded lecture notes of four courses delivered at the workshop are presented, covering the representation theory of finite sets with correspondences, geometric theory of quiver Grassmannians, recent applications of contramodules to tilting theory, as well as symmetries in the representation theory over an abstract stable homotopy theory.The second part consists of six more-advanced papers based on plenary talks of the conference, presenting selected topics from contemporary representation theory: recollements and purity, maximal green sequences, cohomological Hall algebras, Hochschild cohomology of associative algebras, cohomology of local selfinjective algebras, and the higher Auslander–Reiten theory studied via homotopy theory.

Описание:
This comprehensive reference begins with a review of the basics followed by a presentation of flag varieties and finite-dimensional representations in classical types and subvarieties of flag varieties and their singularities. Associated varieties and characteristic cycles are covered as well and Kazhdan-Lusztig polynomials are treated. The coverage concludes with a discussion of pattern avoidance and singularities.
